Alters the size of sprite.
#include <sp.h> /* sp.h */
void spScale(Sprite *sp, s32 xscale, s32 yscale)
It enlarges and reduces the dimension of the sprite.
Expansion makes the sprite look a little blurry.
If you want the "big pixel" look, you could set the TextureFilter mode to do point sampling by using gDPSetTextureFilter(gl++,G_TF_POINT).
Nintendo recommends that you not use scale factors much less than 1.0 for textures with very fine details (for example, text).
